does booting Win Vista works for you? I've tried it but it failed for me.

So, did you hear about Citrix XenServer 5.0?With XenServer installation disc you can make an iso of any OS. You just need to boot from this disc and select "Make VHD image of installed system" function. You can use this way if installed system isn't win-system (Linux, Hackintosh, etc).But the second way is better for windows opearating systems.Second way. With XenServer install disc you can download special utility. And this utility makes a VHD image of installed system. I'm going to do this.
